GEORGE wasnme ron POULTON, or PHILADELPHIA, PENNSYLVANIA, ASSIGNOR F ONE-HALF T0 W. BOSSWILSON,

OF WEST PHILADELPHIA, PENNSYLVANIA.

WINDOW-SASH ATTACHMENT.

delphia and State of Pennsylvania, have invented a new and Improved Window- Sash Attachment, of which the following is a full, clear, and exact description.

My invention relates to an attachment for window sashes.

An object thereof is to provide a simple and inexpensive attachment whereby an ordinary sliding sash can be transformed into a swinging sash. r

A further object of the invention is to provide an attachment whereby the swinging sashes can be utilized as ventilators.

A further object of the invention is'to provide an attachment whereby the sashes can be maintained at predetermined angles, thereby rendering the ventilators adjustable and also permitting the cleaning of the windows from within.

With the above and other objects in view, the nature of which will more fully'appear as the description proceeds, the invention consists in' the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of referenceindicate corresponding parts in all the 'views.

Figure l is an elevation of a window embodying my invention with the window casing partly in section; Fig. is avertical section on line 2-2, Fig. 1; Fig. 3 is a similar section on line 33, Fig. l with the sashes utilized as ventilators; Fig. 4 is a section on line 44, Fig. 6; Fig. 5 is a horizontal section on line 5-5, Fig. 1; and Fig. 6 is a section on line 6-6, Fig. 4.

Referring to the drawings, 7 represents a window casing of any suitable construction in which the lower and upper sashes 8 and9 respectively are mounted to slide. Each of the sashes has its stiles formed of two sections 10 and 11. The sections 10 of the stiles are interconnected by rails 12. It may be said that the members 10 and 12 form a sash, which is pivotally mounted in the supplemental stiles 11, by pivots 13 preferably formed of plates 14 and 14 that may extend through the entire length of the stile sections 10 and 11 or partially as shown Specification of Letters Patent. Application filed August 27, 1915. Serial No. 47,618.

in the drawing. The pivots 13, as will be npted, are provided at the lowermost ends 0 the vertical stile sections 10 and 11. They are formed by embossing the plates 14 and 14, as shown best in Fig. 5 at 15, so as to produce a large bearing surface at the pivots and also to space the plates to accommodate the means for maintaining the sashes at predetermined angles within the window frame 7. Thepivot is formed of a tubular.

member '16 projecting through the embossed parts of the plates 14 and 14 and secured to the plate 1 Thelongitudinal interior edge of the plate 14, secured to the stile section 10, has a flange 17, extending to the plate 14, secured .to the corresponding supplemental stile 11, to bridge the opening or space between the plates romthe interior. The other longitudmal edge of the said plate 14 is folded to form a longitudinal groove 18, engage able by a portion 19 of the longitudinal flange 20 of the plate14. This arrangement of the groove with the flange portion forms a weather strip between the two sections on the exterior side of the window sash which permits the free swinging movement of the window on the pivots to the interior.

The plate 14' has an elongated slot 21 one side of which has indentures' 22. The slotted plate 14 is embossed toward the plate 14 to accommodate the head 23 of 'a bolt 24 rojecting through the slot toward the plate 14. Pivotally mounted on the bolt 24 is an arm 25 the other end of which is pivotally secured to the plate 14 of the corresponding supplemental stile 11. A washer 26 is preferably interposed between the plate 14 and the arm 25. A spring 27 is secured to the arm 25 at the pivotal connection of the arm with the bolt 24, said spring engaging the flange 17 of the plate 14, and tending to move the bolt 24 into engagement with the indentures 22 when the window is moved on its pivot 13.

The sections 10 are maintained locked to the corresponding supplemental stiles 11 by a latch mechanism 28, which prevents an accidental swinging out of the sash from its closed position. The latch 28 comprises a depressible hook 29, secured to the section 10, which snaps automatically against the edge 30 of an opening provided in the part of the latch secured to the section 11 of the stile. A swinging handle 31 is provided in the latch for depressing the hook when it is desired to disengage the section 10 from the supplemental stile 11 for swinging the sash. As

the sash is moved on the hinge from its closed position to its open position the spring 27 causes the bolt 24 to snap into the first indenture 22. By pressing the arm toward the flange 17 the bolt can be brought into engagement with any of the indentures 22 and thereby the sash can be placed at any desired angle to the window frame, thus forming a ventilator which directs the infiowing air upwardly. By moving the sash so as to bring the bolt 24 to the end of the slot 21 the sash can be disposed substantially horizontal to the arm, as shown in Fig. 2, and the exterior side of the glass can then be cleaned from the interior.

It will be noted that the upper window sash 9 is slightly narrower in width than the lower window sash 8, so that the upper sash can he swung between the lower supplemental stiles 11, thus permitting the cleaning of the upper glass, also, from the interior while. standing on the floor. By placing the pivots 13 of the sashes adjacent the lower end thereof the lower sash can, be swung while the upper sash is brought into register with the lower sash; that is to say, no part of the sashproj'ects out of the supplemental stiles 11 when the sash is swung on its pivot. The supplemental stiles 11 being connected with the balancing weights 32 form, in reality, the hanging stile sections of the sash.

When an old window is to be provided with an attachment the vertical stiles of the sashes are sawn vertically to make the sections 10 and 11. The means limiting the movement of the sash in the sections 11 can then be inserted between the sections 10 and 11. In building new windows the sections 11 are, of course, formed independently of the sashes. It will be noted that the win dow sashes can be placed at any point of the window frame and then inclined to the window frame, so that the ventilator formed by the window sashes is not only adjust able to and from the plane of the window frame but also in the plane of the frame, as the sashes can be raised through the medium of'the weights 32 balancing the sashes.

While Ihave described the principle of "operation, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are with.

.having means for engaging the arm at predetermined fixed positions" of the sash on the pivots, the engagement of said plate with'the arm being maintained by the action of gravity on the sash.

2. In a window-sash attachment, the combination of a window sash, supplemental stiles adapted to be suspended, pivotally connectedplates securing the sash to the supplemental stiles so that the pivot is located at the lower end of the sash and whereby said sash can be swung in and out on the supplemental stiles, an arm pivot-- ally secured to one of'theplates, the other plate having a slot engaged by the arm, said slot having indentures, and a pin carried by said arm adapted to be engaged by said indentures under the action of gravity on the sash.

3. In a window-sash attachment, the combination of a window sash, supplemental stiles adapted to be suspended, pivotally connected plates securing the sash to the supplemental stiles so that the pivot of'the plates is located at the lower'end of the sash, whereby the sash can be swung in and out on the supplemental stiles, an arm pivotally secured to oneof the pivotally connected plates, the other plate having a slot engaged by the arm, said "slot having indentures engageable by said arm, and a'spring carried by the arm and engaging the plate having the slot and tending to force said arm into engagement with the indentures.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
